and am currently developing a navigation system with Web server based information and currently I have this Database that contains a table peek hours whose columns are id, start_time, end_time , edge_id, day_of_the_week, edge_weight

 ------------------------------------------------------------------------
|                  Peek Hours                                           |
 ------------------------------------------------------------------------
|    |            |           |         |                 |             |
| id | start_time |  end_time | edge_id | day_of_the_week | edge_weight |
|    |            |           |         |                 |             |

I am using PHP as a webservice and so based on the current time i want to get all the records that would fit this equation

start_time< current_time < end_time

Answer 1

As the other comments suggest, you didn’t look very hard.

 SELECT *
 FROM peek_hours
 WHERE start_time < NOW()
 AND NOW() < end_time

You can also do this:

 SELECT *
 FROM peek_hours
 WHERE NOW() between start_time AND end_time

Although BETWEEN is “less than or equal to”.
